Henkel launches rubber adhesive for intelligent tires

Henkel Adhesive Technologies has launched the latest in its series of Loctite rubber adhesives, dubbed Loctite SI 5930 FIT, for in-tire bonding applications. The product, Henkel claims, would pave the way toward “next-generation tires” with low cavity noise and improved sensor technology. At the same time, there is a growing demand for in-tire bonded sensors to measure performance parameters such as tire pressure, tread depth or contact area.

“A critical requirement of these functional tire designs is the long-term reliable bonding strength of the adhesive material even under severe road, driving and weather conditions,” says Wim Boone, Senior Sales Engineer for Henkel. “Our Loctite SI 5930 FIT product has successfully demonstrated its adhesion performance from the tire production line to over one million kilometers of severe road testing.”

Loctite SI 5930 FIT (for Fix In Tire bonding of acoustic foam and sensors) is a one-component room temperature vulcanizing (RTV) silicone rubber adhesive supplied as thixotropic black paste with a tack-free time of ≤15 minutes, depending on ambient humidity. The material offers excellent adhesion on all common tire rubbers used in the automotive industry, including mixtures for trucks and two-wheelers.
